CONNECTION OF DUCTWORK TO QUARTZ DUCTED FANCOILS
Note:
The provided ducts are there as a means of connecting the ductwork to the fan coil. Following the below steps will ensure
trouble free installation. All ductwork must be in line with the spigots on the unit before securing in position. The ducts
must slide over the spigot connections without having to use excessive force.
Note:
Having to force the duct work to line up with the spigots may cause damage to the spigots and dislodge them from there
fixings.
Typical installation
showing ductwork
connected to unit
The ducts should be pushed fully over the spigot up to the outer casing of the unit and secured to the spigot with screws,
once fitted they should be then sealed around the end of the duct and the outer casing of the fan coil.
IMPORTANT.
The spigots on the unit are there for the sole purpose of providing a connection for the ductwork to the unit. They are not
designed to support the weight of the ductwork and all duct work should be installed square to the spigots this will
eliminate the need for excessive force to make the connection. Duct work should be installed in accordance with CIBSE
HVCA DW144 : Specification for sheet metal duct work.
